Product Description
VI BRICK PRM and VTM modules provide the technical advantages of Factorized Power including high density and efficiency, low noise operation, architectural flexibility, extremely fast transient response, and elimination of bulk capacitance at the point-of-load (POL). Utilizing baseplate and integrated heat sink packaging, the platform also provides improved thermal management and through-hole mounting capability in a small, robust package.
